Total fly ash conditioning system

Features

Benefits

Built to last with a heavy duty container, mixing chamber and an entire unit enclosed to the discharge chute for long, dust-free, worry-free service.

Easy maintenance.

Paddle design ensures maximum wetting of dry material.

Reduced horsepower and low wear rates due to very low RPM.

Easy installation with each complete unit ready for mounting on a prepared foundation.

How it works

Dry ash enters into the rotary feeder and continues into the mixing chamber both to provide an even and constant flow of ash and to maintain the proper material / water ratio.

Water, pressure precisely controlled with an external control valve is sprayed into the ash as it is moved by the mixing paddles. The water is sprayed through specially designed V-jet and hollow cone nozzles which ensure a fine spray and maximum spread and distribution.

Inclined mixing paddle blades, arranged in a helix on a pair of counter-rotating shafts, move material from the bottom of the chamber up each side and force the ash down between the shafts. This action “kneads” the fly ash for maximum exposure of ash to water. The action of the mixing paddles moves the wetted ash from the inlet area to the outlet end of the chamber. The uniformly wet material is discharged through a chute at the bottom of the chamber.

Applications

Ash conditioner applications are:

Fly ash

FGD conditioning

Sludge cake conditioning

Dust wetting

Using a design has been successfully conditioning coal, bark and refuse fly ash in Europe for more than 40 years, engineers have produced a mixer conditioner/unloader that is years ahead of conventional drum-type unloaders.
